In a letter to three Democratic Committee chairmen, White House lawyer Pat Cipollone said the courts have long protected and confidentialized the President's communication with foreign leaders.
"The President Must Be Able to Have Talks with Foreign Leaders Without fearing that these communications will be disclosed and used as food for party political ends," Cipollone wrote in the letter that CNN had received. "And also the leaders of the foreigners must be convinced of it."
The letter from Thursday is the most recent example in which the White House rejected document requests from House Democrats investigating the Trump administration on a number of issues.
"The White House is busy with an unprecedented level of stonemasons, delays and disabilities," Cummings wrote.
In his letter, Cipollone argued that the courts had long respected the executive's right to operate without interference from the legislature's foreign policy.
"Presidents of all political parties have stated that the executive is not legally obliged to convey to Congress documents on confidential diplomatic communication between the president and foreign leaders." He wrote. "No foreign head of state would have private talks with the president or the president's senior advisers if those talks were subject to disclosure (or disclosure to Congressional committees)."
In a sign of growing tensions between the White House and House Democrats, Cipollone, the committees also scolded for "failing to make adequate efforts" to accommodate the interests of the executive.
"It seems that the practice of the committees was to request information for which the committees have no legal right to receive and then unfairly criticize the White House because it simply responds to the consistent bipartisan practices of the White House Past, "he wrote.
